Umu Tipu Hapaira

Ko te sapphire karaihe kotahi he rauemi he nui te pakeke, he pai te pumau matū me te maamaatanga whatu i runga i te whānuitanga o te roangaru. Na enei painga, ka whakamahia nuitia i roto i nga momo umanga tae atu ki te hauora, te miihini, te tuku hoia, te rererangi rererangi, te optics.

Mo te tipu o te sapphire karaihe kotahi te diameter, ko nga tikanga Kyropoulos (Ky) me Czochralski (Cz) te nuinga e whakamahia ana. Ko te tikanga Cz he tikanga whakatipu karaihe kotahi e whakamahia nuitia ana e whakarewahia ai te alumina ki roto i te ipu kakano ka toia ki runga; ka huri te kakano i te wa kotahi i muri i te whakapiri atu ki te mata whakarewa whakarewa, a ko te tikanga Ky e whakamahia ana mo te tipu karaihe kotahi o te sapphire diameter nui. Ahakoa he rite tonu tana oumu tipu taketake ki te tikanga Cz, karekau te karaihe kakano e huri i muri i te pa atu ki te alumina whakarewa, engari ka whakahekea te pāmahana whakamahana kia taea ai e te karaihe kotahi te tipu whakararo mai i te karaihe kakano. Ka taea e tatou te whakamahi i nga hua wera teitei i roto i te oumu hapira, penei i te tungsten crucible, molybdenum crucible, tungsten me te molybdenum parepare wera, huānga whakawera tungsten me etahi atu hua tungsten me te molybdenum motuhake.
